Walmart Black Friday 2010: Will you shop all night?

A woman shops at a Walmart store on "Black Friday" in Oakland, Calif., in 2008. According to the Walmart Black Friday 2010 ads, shoppers can begin getting great deals at midnight just after Thanksgiving Day.

That sale includes a 15.6-inch Hewlett-Packard laptop for $298, an Emerson 32-inch LCD HDTV for $198, and a Magnavox Wi-Fi Blu-Ray player with $10 free VUDU movie credits (a web-streaming service) for $69.

Some Black Friday websites had already posted these deals, even though Walmart had asked that they refrain from doing so.

"Being a partner with Walmart so that we can deliver information to save shoppers time and money, and wanting to respect their request, we have refrained from posting their advertisement for Black Friday," DealTaker wrote in its blog. "Since this company went out of its way to politely ask us not to post it, the least we can do is respect that."

On Monday, Walmart officially released its embargo, allowing competitors to respond with even better pricing, if they can, and customers to catch up on some sleep before the big event at next week's midnight sale.
